Figure 5From: The choice of null distributions for detecting gene-gene interactions in genome-wide association studiesNull distributions obtained using the permutation test. We conduct B = 500 permutations for the AMD data set, as described in the method section. The P-values obtained by the permutation test for models M1, M2, M3, M4 are 0.0040, 0.1180, 0.2880 and 0.1480, respectively. Only model M1 is significant. The claim of the significance of the high order interaction (rs1535891, rs2828151, rs404569, rs380390) based on Model M4 in Table 2 is inappropriate.Back to article page
